"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

"Expertly. The latest ATL cold snap killed my decades old hot water pump when I merely switched my thermostat from Cool to Heat. Common sense drew me to search the internet's reviews for Plumbers near me with the highest rated reviews. Weather Masters was an obvious choice and I have been very impressed with how quickly I was made to feel that I was now their #1 priority. Recognizing my dilema, they worked fast, as we were mere hours before a busy holiday week. I then asked if they might also examine my old rusting A/C unit. At the time of this review, everything has been completed. I am so happy I called Weather Masters. Their work was expertly done, all was performed on my schedule, and most important, was reasonably priced. When working with Weather Masters it was quickly apparent that Jason and Robert's years of experience and practical know how unquestionably contributes daily to Weather Masters operation and outstanding professional results. Thank you so much Kristen*, James, Jason, Robert, Tony, Brian, Jose and Traci, to name a few. You are truly The Best!! *Special Thank You for your extra effort when you made certain my call made to Weather Masters late that Friday afternoon was met with "Yes we can help you.""

Heat pump installations and replacements FAQs

Heat pumps rely on evaporation and condensation processes. The unit transfers heat through the system via a compressed refrigerant. The compressor within the pump circulates the refrigerant through two coils. The first coil evaporates the refrigerant and absorbs warmth from the air. The refrigerant then passes to the second coil, where it condenses, and the unit releases the absorbed heat.

A well-installed and well-maintained heat pump lasts an average of 12 to 20 years. Routine filter changes, annual tune‑ups, and prompt repairs help the equipment reach the upper end of that range, while skipped maintenance or poor installation can shorten its life and raise long‑term costs. Ask your heat pump installation pro for maintenance recommendations so you can get the maximum benefit from your unit.

Heat pumps are most effective in regions where winter lows remain above approximately 40°F. Efficiency starts to drop below that point and falls off sharply near 25°F. If you live in a colder area, look for a model with a high Heating Seasonal Performance Factor (HSPF) and plan on supplemental heat during deep freezes to keep energy use in check.

The biggest drawbacks are the upfront cost and poor cold-weather performance. Installation can require electrical upgrades or duct changes, and once temperatures fall well below freezing, the unit may need help from a furnace or electric resistance coils. Factor in those add‑ons, along with routine maintenance, when you weigh the long‑term savings against the initial investment.
